Abstract
The electromagnetic deflection unit has a support (4) with a flange (8) at its narrow end (5), which has a tangential groove into which merge radial grooves (14). Two sets of deflection coils (18,19) are wound directly onto the support (4). Their turns traverse radial grooves (14). Thence, turns of a set of deflection coils (18) are bent into a tangential groove. The radial grooves (14) have longitudinally extending portions (16), which are filled by the turns traversing them. The bottom portion (20) of the tangential groove lies on the surface of an oval cylinder. The deflection unit has a high sensitivity, a large axial sliding space and large modulation possibilities.
